What two actions can be taken to enable inter-VLAN communications in the data center? (Choose two.)

Layer 3 tunneling is used to extend Layer 2 domains across a Layer 3 network, which does not route traffic between separate VLANs.

Routing protocols advertise Layer 3 network reachability but cannot independently route packets between Layer 2 VLANs without a Layer 3 forwarding device actively performing the routing.

802.1Q trunks carry traffic from multiple VLANs over a single physical link at Layer 2 but do not provide the Layer 3 routing function required to forward packets between separate VLANs.

A router with a Layer 3 interface connected into each VLAN acts as a default gateway for hosts in that VLAN and routes packets to other VLANs by forwarding between its interfaces. This is a fundamental inter-VLAN routing technique where the router provides the Layer 3 boundary between otherwise isolated Layer 2 segments.

A Layer 3-capable switch can be configured with Switched Virtual Interfaces (SVIs) - logical Layer 3 interfaces bound to each VLAN - enabling hardware-speed routing between VLANs. This is the preferred inter-VLAN method in data centers because it combines high port density with integrated routing without requiring a separate external router.
